Software Engineer | C/C++ & Python

Cisco’s interview process typically begins with an online coding test lasting 60‑90 minutes, focusing on data structures, algorithms and problem‑solving speed. Successful candidates move to a technical interview where they discuss their projects, solve live coding problems in C/C++ or Python, and answer networking and Wi‑Fi concepts. The final HR round assesses cultural fit, communication skills and motivation. The overall difficulty is moderate to high, and thorough preparation of coding fundamentals and networking basics is essential.

The Software Engineer role advertised under Cisco Recruitment 2026 is focused on wireless networking software. Candidates will work on the full stack of wireless features that run on access points, controllers and cloud‑managed management platforms. The position blends development, testing and system validation, giving engineers the chance to write production‑grade C/C++ code, automate test suites with Python, and troubleshoot complex network behavior using tools like Wireshark. The role is ideal for fresh graduates or early‑career engineers who are passionate about Wi‑Fi standards, network protocols and building reliable, high‑performance software. Key Responsibilities: 1. Design, develop and integrate new wireless features across access points, controllers and management layers using C/C++ and Python. 2. Create detailed test plans and develop automation scripts to validate functionality and performance. 3. Capture, analyze and interpret logs, packet traces and system metrics to diagnose issues. 4. Reproduce field defects in lab environments and verify fixes across multiple system components. 5. Collaborate with platform, radio, QA and cloud engineering teams to ensure seamless feature delivery. 6. Maintain and enhance existing codebases, ensuring code quality, documentation and adherence to best practices. 7. Set up and manage wireless lab setups for functional and stress testing. 8. Participate in code reviews, design discussions and contribute to architectural decisions. 9. Stay updated with the latest Wi‑Fi standards (802.11ax, WPA3) and incorporate them into product roadmaps. 10. Contribute to continuous improvement of testing frameworks and automation pipelines. Tech Stack: C/C++, Python, Linux, Git, Jenkins, Wireshark, REST APIs, Docker (for lab environments), networking protocols (TCP/IP, UDP, 802.11), security standards (WPA2/WPA3). Growth Path: New hires start as Software Engineers and can progress to Senior Engineer, Lead Engineer, and eventually Principal Engineer or Engineering Manager. Cisco also offers rotational programs across hardware, software and cloud domains, enabling engineers to broaden their expertise. Why Join Cisco?
